MAX30100 – Heart Rate Oxygen Pulse Sensor

Fr 8,000.00


MAX30100 is a multipurpose sensor used for multiple applications. It is a heart rate monitoring sensor along with a pulse oximeter. The sensor comprises two Light Emitting Diodes, a photodetector, and a series of low noise signal processing devices to detect heart rate and to perform pulse oximetry.


  • Operating Voltage – 1.8V to 3.3V
  • Input Current – 20mA
  • Integrated Ambient Light Cancellation
  • High Sample Rate Capability
  • Fast Data Output Capability

Working of the MAX30100 Oximeter

Working of an oximeter:

The sensor consists of a pair of Light-emitting diode which emits monochromatic red light at a wavelength of 660nm and infrared light at a wavelength of 940 nm. These wavelengths are particularly chosen as at this wavelength oxygenated and deoxygenated hemoglobin have very different absorption properties. As shown in the graph below, it can be seen that there is a difference between HbO2(oxygenated Hb) and Hb(deoxygenated Hb) when subjected to these specific wavelengths.
